It is a very good TV I buyed few months ago and now at present it is working very good. It’s model number is 43LH576T and its serial no. ZLD456X0. I buyed this TV because LG is an world Class certified brand. The feature that I like most is screen mirroring I connect my mobile to TV and play games on TV. The speed of TV to catch FPS is very good, it is very fast also. At present there is nothing wrong with my TV and I am satisfied with this TV. I also liked its price which is very good according to its price
